I have made a huge blunder. I have been editing narrative b-roll on one project and interviews on another project. My problem is that the sequence settings on the b-roll differ from that of the interviews. Therefore, copy pasting these clips on the same timeline give me a stretched out picture on my b-roll.
Interview Sequence settings...
